1982 "hodge podge " GMC

My truck started out as a 2 wheel drive , then my cousins boyfreind made it a 4x4 with parts from 78', 79', ect ... He used fulltime axles , its got 1 ton springs in the back ,but basicaly its an 3/4 ton ish He had a 305 in it that came out of a Camaro , i pulled that out and put in a 350 , that a freind helped me rebuild, it has a Pete Jackson gear drive , and i dont remember the specs on the cam , I later added a performer EPS intake and a 750 cfm Edelbrock carb, and it has 202 heads and i believe 4.11 s in the axles... it aint pretty but i can rip all 4 on dry pavement . I still have some bugs to work out though i have done a bunch to it scince I baught it , but havent had the funds to do everything I want to do yet .
